Get the results by trait in model

[karam-mustafa]

I think we can handle the logic for a custom model by adding trait in the model.

example:
instead of using the package in the follwing way

 $instance = (new \SOS\RelationalMetrics\Classes\RelationalMetrics("Store")); 
 $metrics = $instance->getBasicMetrics();

we can get the same result as this example:

$metrics = Store::getBasicMetrics();

and the getBasicMetrics function should be able to call statically or from a new instance of the model
